WILLIAM E. LUDLOVV, OF CLEVELAND, OHIO.

SPECIFICATION forming part of Letters Patent No."758,990, dated May 3, 1904.

Application i'lled February l5, 1904. Serial No. 193,564. (No inodal.)

To all whom it may concern.

Be it known that I, WILLIAM E. LUDLow, a citizen ofthe United States, residing at Cleveland, in the county of Cuyahoga and-State of Ohio, have invented a certain new and useful Improvement in Railway-Trucks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to provide a strong and light truck adapted for railway use. The truck is particularly designed to carry mechanism, such as a drillfor operating upon the rail. rlhe lightness of the truck is a very important feature, allowing it to be easily removed from the track to be out of the way of trains of' cars. To increase the quickness of removal,l provide special derailing-wheels beyond one side of the truck and on axes transverse to those of the main Wheels, so that by raising the other side of the truck it may bev rolled 0E from the track sidewise.

rIhe invention comprises the means adopted for attainingtheaboveobjects,or someof them, as hereinafter more fully explained andV as definitely set out in the claims.

In the drawings, Figure 1 is a plan of my truck. Fig. 2 is a side elevation thereof, and Fig. 3 is a detail illustrating the means for connecting the cross-bars and the main frame of the truck.

The main frame of the truck is ahorizontal rectangle composed of four tubular. bars A A B B, held together at the corners of the rectangle by yokes C. Each yoke has a pair of sleeves c and c, into which the ends of the corresponding tubes project and snugly t. Each yoke has also an arm c2, extending opposite the sleeve c. Axle-pins D extend outward from'each end of the tubes A and have their outer ends supported by the yoke-arms c2. On these axle-pins are journaled the supporting- Wheels E. A pin cmay pass through the sleeve d, the tube A, and the axle D and insure these parts being held in rigid position.

Extending across the uppersides of the bars B, which form the two side members of the truck, are the tubular bars F. These are held p to the bars VB where they cross them by clips G. Each of these clips is as shown in Fig. 3 and consists of a block having through'it two horizontal openings at right angles to each other, Through one opening passes the bar B and through the other the bar F. Set-screws g g', threaded in this block and bearing against the respective bars, may hold the bars F in place.

ing mechanism,as shown atH in Fig. 2. This mechanism rests upon the bars and is clamped to it by suitable U-shaped bolts IL, extending under the bars and passing upward through feet la on the drilling mechanism and having nuts 7a2 above such feet. At the lower end of the mechanism is asuitabledrill-point h3, adapted to operate on the rail. The drilling mechanism carries also a hook L, adapted to extend the yoke C; These two yokes J are connected together by a short tube-section K. Between the yokes are wheels L, journaled on axle-pins N, similar to the pins D. The wheels L have no flanges. Now if the side of the truck opposite the wheels L be lifted up these wheels mayveome into contact with some support, as the pavement P in street-railway work, whereupon the wheel-truck may be easily shoved laterally out of the way after the manner of awheelharrow. Experience has shown that two men can by this means more easily move the truck out of the way than four men could do without this roll-off mechanism. y i 1 To providesuitable -handles for use of the men in rolling off the truck, I simply extend the bars F at the end oppositethe wheels L, as shown at f. The extension of these bars may be greater than shown in Fig. 1, as illustrated by thebreak therein inV Fig. 2. The extended bars f have another function in that Mounted on the bars F may be a suitable drilll the drilling mechanism may be mounted upon them to dowork on the outside of the rail, where switches or other internal obstructions prevent the drilling mechanism from operating from the inne1 side of the rail.

I claiml. A railway-truck composed of four tubular members, yoke-pieces connecting the same, and axle-pins and wheels within the yokepieces.

2. In a railway-truck, in combination, four tubes constituting the sides of a rectangle, horizontal yoke-pieces at the corners of such rectangle, sleeving around such tubes and connected to them, and wheels within the yokepieces.

3. In a railway-truck, in combination, tubular bars, yoke-pieces sleeving around such bars, wheels within the yoke-pieces, and axlepins for said wheels, each pin seating at one end within one of said tubular bars and at the other end in arms carried by the yoke-pieces.

4. In a railway-truck, in combination, tubular bars, yoke-pieces connecting the same, each yoke-piece having an integral sleeve c and an integral sleeve c at an angle thereto in which the ends of the corresponding tubular bars seat, each yoke having a projecting arm c2 opposite the sleeve c', an axle-pin carriedl at one end within the sleeve c' and at the other end by the arm c2, and a wheel on said axle-pin.

5. In a railway-truck, the combination of a wheeled frame, clips secured thereto and crossbars extending through said clips.

6. In a truck, in combination, side bars, yokes rigidly connected to said bars, end bars connected to the yokes, wheels' rotatably mounted within said yokes,intermediate crossbars extending `from one side bar to the other, and clips for securing said cross-bars to the sidebars, substantially as described.

7. rI`he combination of a truck composed of longitudinal bars having yokes at their ends, end cross-bars connecting the yokes on opposite sides of the truck, wheels journaled within said yokes, clips secured to said longitudinal bars, intermediate cross-bars secured to said clips, and mechanism mounted on the crossbars for operating on the rail on which the truck rests.

8. In a railway-truck, in combination, a horizontal tubular frame, clips each consisting of a block perforated in two directions seating on two opposite members of said frame, and cross-bars occupying the other pertorations ot said clips.

9. In a railway -truck, in combination, a horizontal tubular trame, clips each consisting of a block perforated in two directions seating on two opposite members of said frame, cross-bars occupying the other perforations of said clips, and mechanism clamped to said cross-bars and depending to operate upon one of the rails on which the truck rests.

10. In a truck,'in combination, wheels, longitudinal bars, cross-bars, means connecting them, clips secured to said longitudinal bars, intermediate cross-bars secured to said clips, said clips each consisting of a block with two holes through it at right angles, a longitudinal bar passing through one hole and a crossbar through the other, and set-screws carried by the clip for clamping it to said bars, substantially as described.

11. In a railway-truck, the combination with a frame and Hanged supporting-wheels therefor, a member rigidly extending from the frame to one side thereof, and a iangeless wheel journaled in said member on an axis which is rigid with reference to the axes of the supportiiig-wheels and is at right angles thereto.
